While the FETCHERS are at the Tinki Treehouse, there is a Buddy The T-Rex cardboard sign on the Tinki Treehouse. This is a reference to another PBS Kids/KERA Kids TV Show ''Dinosaur Train'' in which one of those characters in that TV Show is Buddy The T-Rex.

This is the last episode of the entire series ending the journey of Ruff Ruffman and the FETCHERS.

PURRS headquarters takes place in Water Country on one of those houses in Nevena. Intersting Water Country is also the same water park where all the water rides live.

Also, Water Country is the only water park for Nevena.

Also, in this episode one of the houses have PURRS headquarters but if you go to that house that used to have PURRS headquarters, you can see PURRS headquarters is no longer there and instead just a standard house without PURRS headquarters.

Also, the Water Country logo is old before changing it to the new logo in 2013.

Studio P/PURRS Headquarters/Go Get It! Garage is very simlar to Studio G/The Garage, but with the Go Get It! stuff instead of the FETCH! With Ruff Ruffman stuff and, like Ruff Ruffman says "they painted it pink.".

Studio P/PURRS Headquarters/Go Get It! Garage and Go Get It! in this episode shares many references to the other FETCH! With Ruff Ruffman episodes before this episode was premiered.

Send in the Clowns: In "Send in the Clowns",Ruff Ruffman said "Go Get It!" twice. A reference to the copy-cat cat TV Show "Go Get It!".

Doggie Duties: In "Doggie Duties",Ruff Ruffman said "It's Studio P Liza!" to Liza after she said "The Garage" before he'd correcting it to Studio G. A reference to Studio P/PURRS Headquarters/Go Get It! Garage in this episode.

After Ruff Ruffman finished his farewell song, Chet is wearing his pilot suit and then used his parachute after the plane crashed and then the plane's black smoke appears. A reference to the intro used in every Season 4 and Season 5 episodes where in that intro, Chet is wearing his pilot suit and then used his parachute after the plane crashed and then the plane's black smoke appears.

Also, this the only episode in the series that is the not the Season 4 and Season 5 intro that the episode used the intro's Chet's airplane and pilot suit technique intro in this episode and any episode of the FETCH! With Ruff Ruffman series.

The episode is called "The Fetch! Finale". Which is fitting, since the title of the episode is all about the show's series finale.
